Bob Twiggs Keynote Address at 2024 AMSAT Space Symposium Now Available
For those who missed Bob Twiggs, KE6QMD, keynote address at the 2023 AMSAT
Space Symposium, now is your chance to catch up on this delightful and
informative presentation. You can view BobâÖs 36-minute presentation
at
https://youtu.be/uDPJ4SHAF74?siÉf3xM8G1KFUjZPw. Sorry, there are no
advanced mathematical formulas or complex orbital mechanics to be found
here. Bob is a consummate story teller who brings warmth and humanity to
the pioneering days of amateur satellites. If you werenâÖt in Dallas
for the
live event, this is the next best thing to being there.
Robert J. Twiggs is a professor of Astronautics and Space Science at
Morehead State University. He is responsible, along with Jordi Puig-Suari
of California Polytechnic State University, for co-inventing the CubeSat
reference design for miniaturized satellites which became an Industry
Standard for design and deployment of the satellites.
Twiggs earned a Bachelor of Science in Electrical and Electronics
Engineering from the University of Idaho in 1961 and a Master of Science in
Electrical Engineering with a concentration in microwave devices from
Stanford University in 1964.
>From 1985 to 1994, Twiggs was the director of the Weber State University
Center for Aerospace Technology. He served as a consulting professor in the
Stanford University Department of Aeronautics and Astronautics from 1994 to
2008. At Stanford, he established the Space Systems Development Laboratory.
Bob Twiggs became a professor at Morehead State University in 2009 in an
effort to push the PocketQube standard leveraging the universityâÖs
large
aperture space tracking system, and to help develop a space economy in the
state of Kentucky.
In 2019, Twiggs designed and proposed another smaller, simpler satellite
form factor called ThinSat which could enable high school students to
design and build satellites.

Updated Hamfest Handouts Now Online
Realizing that the hamfest season runs from January 1st through December
31st every year, AMSAT needed to update its venerable tri-fold handout.
While AMSAT finalizes its plans for reinvigorating its Ambassador program,
it wanted to make immediately available a fresh set of handouts for use at
hamfests, maker-faires, and so on.
Some of the considerations to be factored into an updated program are the
increased costs of printing and shipping small quantities of handouts here
and there. Conversely, the cost of printing and shipping literature has to
be balanced against the inevitable âwasteâ factor of litera
ture simply
tossed into, at best, a nearby recycling bin by passer-byâÖs who fee
l
obligated to take a handout offered to them as they walk by a display.
Considerable thought is being given to this situation.
For a few recent hamfests, a few AMSAT Ambassadors have been testing the
concept of displaying a poster with a QR code that interested parties can
scan to download literature. Although it is too soon to say this approach
is a smashing success, AMSAT Ambassadors testing the concept feel positive
about the reaction of hamfest participants visiting their displays. In
tests, a QR code on a small poster can be successfully decoded at up to 20
feet away.
You can view or download the QR code poster at AMSAT Hamfest QR Code
<https://www.amsat.org/wordpress/wp-content/uploads/2024/02/Scan-Here-QR-Po
ster-Hamfest_85x11_240123.pdf>
.
The QR code used brings the ham to a âlandingâ site of the
AMSAT website.
The landing site offers the person
- A link to join AMSAT online,
- A two-page summary brochure as to why they should join AMSAT,
- A comprehensive brochure describing AMSAT activities, and
- A link to the AMSAT Store to buy a downloadable copy of âGetti
ng
Started with Amateur Satellites.â
You can view the landing page at
https://www.amsat.org/getting-started-with-amsat/. This page has been
specially formatted for use on smart phones. You can click on each of the
images to view or download each of the documents or links. Since this is a
test period for this approach, these pages are not cataloged on the web
site. After we receive feedback from AMSAT membership and especially AMSAT
Ambassadors, access to these documents and the QR code poster will be open
to general membership.
The AMSAT Ambassador team looks forward to your feedback on how to improve
AMSATâÖs presence at local and regional hamfests, maker-faires and o
ther
events that can boost interest in amateur satellites and AMSAT membership.
Please send your comments and/or questions to info@amsat.org. If you are
interested in becoming an AMSAT Ambassador, please send an email with a
short resume to volunteer@amsat.org.

UKâÖs SaxaVord Spaceport to Launch Amateur Radio Satellites
Two more amateur radio satellites, MARIA-G (HADES-F) and UNNE-1 (HADES-E),
are planned to launch from the UKâÖs SaxaVord Spaceport later in 202
4.
Previously announced amateur radio payloads on the launch are:
ERMINAZ-1U and -1V from AMSAT-DL
GENESIS-MA and -ME from AMSAT-EA
QUBIK 5, SIDLOC-PQ-1 and -PQ-2 from Libre Space Foundation
*MARIA-G*
A 1.5u Pocketqube. MARIA-G will offer radio amateurs around the world the
opportunity to relay FM voice and AX.25 / APRS 300 / 1200 bps
communications. The satellite will also transmit telemetry with its status
and voice and CW messages. This all will be achieved by implementing a SDR
based FM and FSK repeater. The FM / FSK repeater will be available all time
and opened by squelch level without the need of a PL tone/CTCSS.
Main mission for MARIA-G is to be a FM repeater but it will also include a
simple guess game being implemented by students at Maria Guerrero High
School in Collado Villalba â Madrid (Spain). The satellite will sen
d a clue
each week in CW so radio amateurs will have to solve the mystery by having
all the clues.
A small experiment, developed by Fraunhofer-Gesellschaft research
organization (Germany) will also fly on the satellite to make proof of
concept transmissions of a TS-UNB waveform from a low Earth orbit. It will
transmit a TS-UNB message according to the ETSI standard ETSI-TS-103-357.
It is intended solely as a research and development project with no
commercial intent, all its data public and open. ITU modulation
classification would be 100K W2DWW but the bandwidth will be narrowed. The
operation of this experiment will be managed by AMSAT-EA.
*UNNE-1*
A 1.5u Pocketqube. UNNE-1 will offer radio amateurs around the world the
opportunity to relay FM voice and AX.25 / APRS 300 / 1200 bps
communications. The satellite will also transmit telemetry with its status
and voice and CW messages.
This all will be achieved by implementing a SDR based FM and FSK repeater.
The FM / FSK repeater will be available all time and opened by squelch
level without the need of a PL tone/CTCSS.
A small guessing-game is being implemented by students of Universidad de
Nebrija (Spain). The satellite will send a clue each week in its telemetry
so radio-amateurs will have to solve the mystery by having all the clues.
Game will be detailed in AMSAT-EA and Universidad de Nebrija websites.
The main mission for the satellite is acting as a FM voice repeater
although due to its SDR nature it can repeat data too. This satellite is
based on the hardware of HADES-D (SO-121) thatâÖs currently being us
ed to
amateurs worldwide. The guess game implemented by the University is a small
challenge for the radio-amateurs and its mission is to make the reception
of signals from the satellite fun for youngsters, expecting them to be
future radio amateurs.
Proposing a UHF downlink, VHF Uplink for FM voice, FSK data up to 1200 bps,
APRS up to 1200 bps and FSK telemetry and experimental data up to 1600 bps
and CW.
These two satellites are part of the Erminaz mission, a joint effort by
AMSAT-DL, AMSAT-EA and Libre Space Foundation. Planning a DLR/ESA launch
from the UK SaxaVord Spaceport in Summer 2024 into 500/600 km polar orbit.

AO-73 Goes on Hiatus
A messages from the FC1 operations team reads,
âAfter a good period of transponder activity FUNcube batteries need
a short
rest. We plan to switch the transponder OFF between March 3rd to 15th
subject to operational conditions. The satellite will be placed Safe mode
and will still provide low power telemetry

Bochum Space Conference 2024
>From September 20-22, 2024, AMSAT-DL is organizing a symposium, flea market
and general meeting in the radome of the Bochum Observatory. The radome
will once again be dedicated to satellite and space research.
AMSAT Deutschland e.V. and the Bochum Observatory are taking the positive
experience of the anniversary conference in 2023 as an opportunity to
inform AMSAT members and other space enthusiasts about current and future
prospects for national and international space projects with a varied
program. As the radome is also the location of ESAâÖs education offi
ce in
Germany (esero Germany), they want to make the symposium even more
attractive in future and at the same time focus even more on current
European space travel.
The planning so far envisages the following schedule:
Friday, September 20, 2024
Come-together in the afternoon including short guided tours in the radome.
Saturday, September 21, 2024
>From 9:00 a.m. AMSAT symposium with lecture program. Amateur radio flea
market in the radome.
Sunday, September 22, 2024
>From 10:00 a.m. General meeting
Further information on the AMSAT-DL space conference in Bochum will follow
in the course of 2024. The conference program is expected to be available
on our website beginning in July. Speakers with interesting topics wanted,
please get in touch!

Changes to AMSAT-NA TLE Distribution for February 23, 2024
Two Line Elements or TLEs, often referred to as Keplerian elements or keps
in the amateur community, are the inputs to the SGP4 standard mathematical
model of spacecraft orbits used by most amateur tracking programs. Weekly
updates are completely adequate for most amateur satellites. Elements in
the TLE bulletin files are updated daily. TLE bulletin files are updated to
add or remove satellites as necessary Thursday evenings around 2300 UTC, or
more frequently if new high interest satellites are launched. More
information may be found at
https://www.amsat.org/keplerian-elements-resources/
The following satellites have been removed from this weekâÖs AMSAT-N
A TLE
distribution:
CAPE-3 NORAD Cat ID 47309 Decayed from orbit on or about 17 February 2024
GRIFEX NORAD Cat ID 40379 Decayed from orbit on or about 22 February 2024

ARISS NEWS
Amateurs and others around the world may listen in on contacts between
amateurs operating in schools and allowing students to interact with
astronauts and cosmonauts aboard the International Space Station. The
downlink frequency on which to listen is 145.800 MHz worldwide.
*Completed Contacts*
Girl Scout Troop 1089, Sacramento, CA, direct via N6NA.
The ISS callsign was NA1SS.
The crewmember was Loral OâÖHara, KI5TOM.
The ARISS mentor is AA4KN.
Contact was successful on Thursday February 22, 2024.
The crossband repeater continues to be active (145.990 MHz up {PL 67} &
437.800 MHz down). If any crewmember is so inclined, all they have to do is
pick up the microphone, raise the volume up, and talk on the crossband
repeater. So give a listen, you just never know.
The packet system is reported to be active on the ARISS status page
(145.825 MHz up & down) but the AMSAT satellite status page shows no recent
contacts as of the time of this writing.
As always, if there is an EVA, a docking, or an undocking; the ARISS radios
are turned off as part of the safety protocol.
Note, all times are approximate. It is recommended that you do your own
orbital prediction or start listening about 10 minutes before the listed
time.
The latest information on the operation mode can be found at

Satellite Shorts From All Over
+ The European Space Agency AcademyâÖs CubeSat Summer School is open
for
applications. Taking place over four weeks from 5 to 30 August 2024 at
ESEC-Galaxia (Transinne, Belgium), applications are now open for university
students with engineering, physics and business management backgrounds.
During the Summer School, ESA and external experts will deliver an
extensive mix of lectures and hands-on activities. The entire project
lifecycle of a satellite mission will be covered, from design to
verification, launch and operations, including typical milestone reviews
and new methodologies. Students will be introduced to legal, cybersecurity,
and economic aspects of space projects. The Summer School will even
introduce space entrepreneurship skills, offering support in devising
methods of turning a CubeSat into a viable and profitable business
opportunity. More information at
http://tinyurl.com/ANS-056-ESA-Summer-School. [ANS thanks the European
Space Agency for the above information.]
+ NASA is developing a plan to deorbit the International Space Station
(ISS) at the end of its lifetime, currently scheduled for 2030. Since the
356-foot-wide laboratory is too big to completely vaporize if left to
naturally burn in EarthâÖs atmosphere, the space agency intends to s
end a US
spacecraft to help deorbit the station and direct its reentry over the
unpopulated South Pacific. The goal is to give the ISS an extra âsp
ace tugâ
to help it move more than it could with its own thrust, and guide the final
burns for ISS to re-enter EarthâÖs atmosphere. The space tug is expe
cted to
cost $1 billion, agency officials had said earlier this year. Earlier this
year, Russia agreed to stay onboard ISS through 2028, rather than its
previous timeline of 2024, after which it may focus on building its own
station in low-Earth orbit. Other partner countries have agreed to continue
their presence through 2030, but it is not clear precisely how they will
contribute to retiring the ISS. More information at
http://tinyurl.com/ANS-056-ISS-Tug. [ANS thanks the SpaceRef.com for the
above information.]
+ Martians Wanted: NASA has opened the call for a simulated yearlong Mars
mission. If youâÖre looking for an extended vacation next year, NASA
is
seeking applicants to participate in its next simulated one-year Mars
surface mission to help inform the agencyâÖs plans for human explora
tion of
the Red Planet. The second of three planned ground-based missions called
CHAPEA (Crew Health and Performance Exploration Analog) is scheduled to
kick off in spring 2025. Each CHAPEA mission involves a four-person
volunteer crew living and working inside a 1,700-square-foot, 3D-printed
habitat based at NASAâÖs Johnson Space Center in Houston. The habita
t,
called the Mars Dune Alpha, simulates the challenges of a mission on Mars,
including resource limitations, equipment failures, communication delays,
and other environmental stressors. Crew tasks include simulated spacewalks,
robotic operations, habitat maintenance, exercise, and crop growth. More
